Stylish and Comfortable

I loved this top so much, I purchased a second one. I wear it for both skiing and cycling. Keeps me warm, dry, and comfortable. Plus it looks great!

Great length, coverage

I'm 135lbs/5'6 and this fits me perfectly in a small. I typically wear an xs/s, usually small in cycling gear. I could see if you are well-endowed that this may be tight across the chest. Kept me super warm for ice skating with just one more fleece layer on top. It's actually a bit too warm to layer for cycling when it's about 0 degrees C. Great wicking. The extra long rear hem and sleeve lengths are perfect for my size and leaning over and ensuring no cold draughts get in.


Great base layer which is super comfy, warm and even quite flattering. I wore it under a top whilst working from home, it kept me cosy so that I bought another one. Very comfy for winter cycles, walks etc too

Don't want to take this off

I've yet to take it out for a spin, but I can already tell this is gonna be a great base layer. The tee on its own rides up a little bit, but when stuffed in my trousers (which they're gonna be anyway) it's all good! Gonna be wearing this for cycling, hiking and just around the house. I got a size M, which is my usual size and it fits like a glove.

Super cycling base layer

Perfect fit, excellent value for money. Nice and long at the back, great freedom of movement. Kept me very cosy without being bulky.

XL size no good if you have been blessed with dd's

Like others have mentioned it's a quality item and would be great...if only it would fit. Not in stock at my local store so had to travel across London the collect so that even more annoying, but they will have to be returned as I just cant breath in them.

Sizing not great

Bought the L/XL. It's way too tight. Gave it away

Expensive straight Jacket

Decathlon really need to look at their UK sizes i bought a L/XL and when I eventually got into it it created the most incredible mono boob / squashed pancake chest I've ever encountered. It appeared to work on the ride there was a definite increase in heat, although that could've be attributed to the extra effort needed to breath! Post ride recovery saw me do a large assortment of stretching exercises just to get the thing off my pilates instructor would have been proud. I'd love to rate it highly but the simple fact of poor choice of UK appropriate sizes suitable for commuter type riding leaves me not only disappointed but infuriated that a £20 technical under layer is probably going to collect dust under my bed as I don't think ill be wearing it anytime soon.

Good base layer

Tried as a general base layer and it was really comfy. The shape at the back will be good for cycling too.

Additional Product Information


Main fabric

  • 55% Polyester cationic
  • 42% Polyamide
  • 3% Spandex

Reduced chafing

The seamless design is achieved by knitting the fibers in a tube, which avoids the need for side seams and ensures complete comfort!

Moisture management

This base layer has ventilated areas under the arms, on the chest and at the sides to improve wicking and dry more quickly. It therefore retains heat when worn against the skin as a base layer (underneath a long-sleeved jersey)

A rating to compare products' environmental impact

A product's environmental impact is calculated for its entire lifecycle using various indicators. Products are then given an ABCDE rating to help you easily identify products having the best environmental performance (lowest impact) by comparing different products of the same type (T-shirts, bottoms, backpacks, etc.). Decathlon voluntarily chooses to display the environmental ratings of its products. Web: Explanation video:
